Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00076 | $0.01144 |
| Opus 5 | $0.00038 | $0.00572 |
| Sonnet 5 | $0.00015 | $0.00229 |
| Haiku 4.5 | $0.00008 | $0.00114 |
Grade A, and why
home-assistant-integration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Home Assistant Integration Skill
Use this skill for Home Assistant custom integration development. This is separate from Home Assistant automation, helper, script, and Lovelace work.
Start With Current Docs
Fetch the latest markdown from the Home Assistant developers docs repository before coding. All doc paths in this skill and its references are relative to this base URL — prepend it when fetching:
https://raw.githubusercontent.com/home-assistant/developers.home-assistant/master/docs/
Use rendered pages on developers.home-assistant.io only as secondary reading. Do not copy Home Assistant docs into generated skill or repo files. Fetch only the files relevant to the task.
The reference files in this skill are the routing indexes to the doc paths; do not rely on remembered Home Assistant APIs. Always consult the relevant reference, then fetch the current markdown files it points to, before editing matching files:
| Reference | Use when |
|---|---|
references/architecture.md |
Editing generic integration architecture, lifecycle, setup, manifest, config entries, data fetching, events, diagnostics, auth, networking, docs, tests, or translations |
references/core-integration-files.md |
Editing core integration files such as __init__.py, manifest.json, config_flow.py, coordinator.py, diagnostics.py, repairs.py, services, translations, tests, or docs |
references/entities-and-domains.md |
Editing platform/entity files such as sensor.py, binary_sensor.py, calendar.py, weather.py, or deciding which platform domain fits a feature |
references/automation-triggers.md |
Adding or maintaining new integration-provided automation triggers in trigger.py and triggers.yaml |
references/quality-rules.md |
Checking Bronze/Silver/Gold/Platinum quality scale rules or reviewing an integration against Home Assistant quality requirements |
What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

home-assistant-integration is a skill published in the GitHub repository denysdovhan/agents (17 stars, last pushed 1mo ago), licensed MIT. It adds 76 tokens to every session and 1,144 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
